Benefits of technology
The patent describes a technology that improves the accuracy and user experience of biometric authentication in electronic devices. This means that users can be authenticated more accurately using their unique physical features, such as fingerprints or facial features. The technology also ensures that users are not inconvenienced when changing or updating the matching algorithm for biometric authentication. Overall, the technology improves the speed and accuracy of biometric authentication in electronic devices, making it a more convenient and user-friendly experience.
Problems solved by technology
However, if the existing reference biometric information is deleted, normal biometric authentication is not possible until effective new reference biometric information is re-registered.
Thus, user inconvenience may occur due to authentication failure.
Further, to configure new reference biometric information, there may be inconvenience in that the user has to re-register biometric information.

An electronic device includes at least one processor connected with a biometric sensor and memory, and configured to perform biometric authentication using a first matching algorithm and a first template DB, install a second matching algorithm and a second template DB and set the second template DB to an inactive state, determine whether a predetermined template registration condition is met when biometric authentication using the first matching algorithm and the first template DB is successful, generate a template including input biometric information of the successful biometric authentication and register the template in the second template DB in the inactive state in case that the template registration condition is met, set the second template DB to an active state in case that the second template DB meets a predetermined template activation condition, and perform the biometric authentication using the second matching algorithm and the second template DB in the active state.
Description
CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a bypass continuation of International Application No. PCT / KR2021 / 015455, filed Oct. 29, 2021, which claims priority to Korean Patent Application 10-2020-0146853, filed Nov. 5, 2020, the disclosures of which are herein incorporated by reference in their entirety.BACKGROUND1. Field[0002]Various embodiments relate to electronic devices for biometric authentication and methods of operating the same.2. Description of Related Art[0003]As the importance of protecting personal information increases, an electronic device uses a user authentication scheme to enhance security. Various security authentication schemes, such as password, pattern, and biometric authentication, may be used for user authentication. Among them, biometric authentication may be performed based on the user's biometric information, which are unique physical characteristics, such as the user's fingerprint, iris, face, voice, retina, blood vessel, and the li...
